Welcome to the Quantum Speaker Mini BLEND pack
Featuring the Celestion G12H-150 “Redback”
This NAM Profile pack is designed to give you a glimpse into what Quantum Speaker (QS) technology is truly capable of.
Quantum Speaker is not just about capturing the sound of a speaker — it’s about recreating the non-linear behaviour, phase interaction, and dynamic response of a real cabinet recorded in a professional environment. It captures the true sound and feel of a speaker being mic’d up in a studio by expert engineers.
Speaker Bio: Celestion G12H-150 “Redback”
The G12H-150 Redback is a 12" ceramic magnet speaker introduced by Celestion in 2017, designed to combine high power handling with a refined tonal balance.
Power Rating: 150 watts
Frequency Range: 70Hz–5kHz
Sensitivity: 100dB
It delivers a powerful low end, balanced midrange, and smooth treble, maintaining clarity and articulation even at high volumes or under heavy gain.
What’s Inside
This free mini sample pack contains four discrete microphone captures, each taken from a real-world studio session using the same methods trusted by professional engineers.
These are raw, untreated mic profiles — no EQ, no post-processing, and no artificial enhancement. The result is a natural, accurate representation of a mic’d cabinet that behaves just like the real thing.
Contents
Dynamic Mic (centred) – capturing a tight, focused response
Ribbon Mic (on the cone) – delivering warmth and tonal depth
Room Mic – adding space, dimension, and realism
Proprietary Sub Transducer – designed for low-end energy and movement
Why This Matters
Each mic is profiled individually, offering true-to-life mic behaviour you can blend in your DAW — phase, dynamics, and non-linear response all fully intact.
These are discrete profiles, not static snapshots or approximated EQ curves. The realism comes from our proprietary NDX profiling system, which captures not just the tone, but how the sound behaves and evolves over time.
How to Use
Load the four mic profiles into your DAW or profiler using the Neural Amp Modeler (NAM).
Blend them together just like you would in a real session — fader-style, in parallel.
Shape the sound freely. Each mic retains its integrity, allowing nuanced tone crafting without phase issues or artificial constraints.
Important Note
If you’ve used our QuickStart files, you’ve already heard the enhanced realism Quantum Speaker provides in a simplified, ready-to-play format. This pack goes deeper — giving you true control, creative flexibility, and a chance to experience what real mic blending feels like inside the box.
The full Quantum Speaker packs include 27 individual mic profiles, expanding your options and unlocking the full power of the Quantum Speaker system. This mini pack is your first step into that world.
